The past three nights of data I’ve received from AAVSONet OC61 (6/29, 7/1 and 7/7) have severe clipping issues. Only the cores of the brighter stars are visible and the background has a pixel value of -500 on all images. There is no astrometry info in the FITS header either.

The issues I was having with clipping continue. All images from OC61 have average background pixel values of -500 or -350 ADU. The images from the last couple weeks do have astrometry info in the FITS header, which was missing 3-4 weeks ago. Another issue I noticed is that the “B” filtered images look just like the “V” images, except with a longer exposure. Does anyone know who to contact about these issues? Who is currently overseeing OC61?
